Learn the basics about the covalent bonding of water, when learning about covalent bonding within properties of matter. Water is made from one oxygen atom and two hydrogens. The oxygen has 6 electrons in its outer shell, but it really wants to have 8 to have a full shell. The hydrogens have one outer shell electron, but want to have two. The atoms share their electrons, forming covalent bonds. So all three atoms have full outer shells, and create a water molecule. Water has two covalent bonds. In water, the bonding electrons spend most of their time nearer the oxygen atom, because it is more ELECTRONEGATIVE. This means that it is electron withdrawing. As the negatively charged electrons are nearer the oxygen atom, the oxygen atom becomes a little bit negative itself, while the hydrogens become a little positive. This is called delta positive and delta negative. Water doesn’t just have any old covalent bonds; it has what we call POLAR COVALENT bonds and is a POLAR molecule. This is really important as it affects how water behaves and reacts with other elements. SUBSCRIBE to the Fuse School YouTube channel for many more educational videos.

In this video we discuss hydrogen bonds. We cover how do hydrogen bonds form, the different elements that take part in hydrogen bonds, and why doesn't oil and water mix. What are hydrogen bonds? An attractive force called a hydrogen bond can exist between certain molecules. These bonds are weaker than ionic or covalent bonds, because it takes less energy to break these types of bonds, however, a large number of these bonds going on can exert a strong force. Hydrogen bonds are the result of an unequal charge distribution on a molecule, these molecules are said to be polar. If we look at a water molecule, we can see the oxygen atom shares electrons with 2 different hydrogen atoms. So, in total this molecule has 10 protons, 8 from oxygen and 1 each from the hydrogen atoms, and a total of 10 electrons, 2 shared between the oxygen atom and hydrogen atom number one, 2 shared between the oxygen atom and hydrogen atom number 2, and the other 6 non shared electrons from the oxygen atom. So, this water molecule is electrically neutral, but it has a partial positive side, the hydrogen side, and a partial negative side, the oxygen side of the molecule. The electrons are not shared equally within the molecule, as they have a higher probability of being found closer to the nucleus of the oxygen atom, giving that end a slightly negative charge. So, the hydrogen atoms end of the molecule will have a slightly positive charge. These charged ends weakly attach the positive end of one water molecule to the negative end of an adjacent water molecule. When water is in liquid form there a few hydrogen bonds, solid form, many bonds, and when water is steam or gas, there are no bonds, because the molecules are too far apart to form any bonds. Hydrogen bonds only form between hydrogen atoms that are covalently bonded, or bonds where electrons are being shared and not transferred, to an oxygen, nitrogen or fluorine atom. These bonds make water ideal for the chemistry of life. Hydrogen bonds are also important in the structure of proteins and nucleic acids, which we will cover in later videos. So, now we know that water molecules are polar, or have slightly positive and slightly negative ends, and in fact, many lipids, or fats and oils, are not polar. So their molecules share electrons equally in their bonds. So, these are nonpolar molecules. This means that when water and oil come together they do not form bonds with one another. Even when we try to mix them, the water molecules will eventually separate because their polar molecules are attracted to one another and will form hydrogen bonds, separating the water and the nonpolar oil molecules.

This chemistry video tutorial provides a basic introduction into hydrogen bonding. Hydrogen bonding occurs in molecules when hydrogen is attached to highly electronegative small atoms such as nitrogen, oxygen, and fluorine. Hydrogen bonds are very strong dipole dipole interactions. Molecules that contain hydrogen bonds such as water are very polar. Hydrogen bonds is one of the strongest types of intermolecular forces. This video contains a few examples and illustrations of hydrogen bonds in water and in HF.

water special molecule है..इसे बनाने वाले different elements के बीच की bonding इसे special बनाती है. शायद आपको पता ही होगा कि सभी elements की tendency, अपना octate complete करने की होती हैं. इसकी detailed study के लिए आप हमारा ये video देख सकते हैं! water..एक oxygen और दो hydrogen atoms का combination होता है. oxygen की outer shell में 6 electrons होते हैं..यानी इसे अपना octate complete करने के लिए 2 electrons की जरूरत होती है. वहीँ hydrogen की outer shell में एक electron होता है..और इसे valence shell full करने के लिए एक extra electron की जरूरत होती है! ये दोनों atoms अपना octate complete करने के लिए आपस में electrons की sharing करके covalent bonds बनाते हैं. hydrogen और oxygen के बीच इस तरह की bonding होने से हमें water molecule मिलता है! electrons की sharing से बनने वाले covalent bonds को हम इस तरह straight line से represent कर सकते हैं..लेकिन वास्तव में water molecule को हम इस तरह draw नहीं करते! इसकी actual geometry ये है. water की ऐसी geometry, oxygen के loan pairs के कारण होती है. ये unshared loan paires..bonding pairs को repell करते हैं. जिससे oxygen atoms नीचे की तरफ shift हो जाते हैं.

THANKS! *** Molecules come in infinite varieties, so in order to help the complicated chemical world make a little more sense, we classify and categorize them. One of the most important of those classifications is whether a molecule is polar or non-polar, which describes a kind of symmetry - not just of the molecule, but of the charge. In this edition of Crash Course Chemistry, Hank comes out for Team Polar, and describes why these molecules are so interesting to him. You'll learn that molecules need to have both charge asymmetry and geometric asymmetry to be polar, and that charge asymmetry is caused by a difference in electronegativities. You'll also learn how to notate a dipole moment (or charge separation) of a molecule, the physical mechanism behind like dissolves like, and why water is so dang good at fostering life on Earth. -- Table of Contents Charge Assymetry & Geometric Asymmetry 01:33 Difference in Electronegatives 01:49 Hank is Team Polar 00:33 Dipole Moment 03:49 Charge Separation of a Molecule 04:12 Like Dissolves Like 04:41 Water is Awesome 05:10 -- Want to find Crash Course elsewhere on the internet?

The polar nature of water gives it some important properties. It allows things to dissolve in it. It has a high specific heat capacity. It’s got a high heat of vaporisation. Water molecules are cohesive meaning they can stick to each other. They are adhesive meaning they can stick to other things. Water has a high surface tension. And because hydrogen bonds force solid water to form in a crystalline structure, ice is less dense than water and therefore it floats.

Water is made up of one oxygen atom, and two hydrogen atoms. And looks something like this. This structure makes water a very polar molecule. Without going into the beautiful details, Oxygen has a net negative charge while the opposite ends with the hydrogens have a net positive charge. This allows water molecules to form hydrogen bonds and gives water many of its other properties. Cohesion and Adhesion are two such properties. Cohesion is water’s attraction to itself. The hydrogen bonds that I mentioned facilitate this. This is also why water has surface tension, allowing bugs to walk on it. Additionally, cohesion keeps water a liquid at moderate temperatures instead of a gas. Adhesion is water’s attraction to other surfaces. Water will adhere to anything it can form a hydrogen bonds with. This is the reason for capillary action, where water climbs up a narrow glass tube. Another property of water is it’s high heat capacity. Heat capacity is a substance ability to absorb heat. More accurately, it’s the amount of energy needed to raise one gram of a substance by one degree celsius. This allows water to absorb temperature changes and keep air temperature at moderate levels. Which is pretty cool… Finally, water is known as the universal solvent, meaning that a wide range of substances can be dissolved in it. This includes hydrophilic and polar molecules like sugars and salts. Substances that generally don’t dissolve in water are hydrophobic, like oils. So now you know a little more about the properties of H2O, and bare in mind, we only covered a portion of water’s amazing properties, so be sure to check the links in the description to learn more.

There are four types of chemical bonds essential for life to exist: Ionic Bonds, Covalent Bonds, Hydrogen Bonds, and van der Waals interactions. We need all of these different kinds of bonds to play various roles in biochemical interactions. These bonds vary in their strengths. In Chemistry, we think of Ionic Bonds and Covalent bonds as having an overlapping range of strengths. But remember, in biochemistry, everything is happening in the context of water. This means Ionic bonds tend to dissociate in water. Thus, we will think of these bonds in the following order (strongest to weakest): Covalent, Ionic, Hydrogen, and van der Waals. Also note that in Chemistry, the weakest bonds are more commonly referred to as “dispersion forces.” Related Chemistry video: Ionic Bonds vs Covalent Bonds http://bit.ly/2cUG6C8 Our series on Biology is aimed at the first-year college level, including pre-med students.

There are two different types of hydrogen bonds. They are Intermolecular bonding and Intramolecular bonding. i) Intermolecular hydrogen bonding. This type of bond is formed between the two molecules of the same or different compounds. Some examples of the compounds exhibiting intermolecular hydrogen bonds are : Hydrogen fluoride and water. 1. Hydrogen fluoride, H F. In the solid state, hydrogen fluoride consists of long zig-zag chains of molecules associated by hydrogen bonds as shown in the figure. Therefore, hydrogen fluoride is represented as HFN. 2. Water In water molecule, the electronegative oxygen atom forms two polar covalent bonds with two hydrogen atoms. The oxygen atom due to its higher electronegativity acquires partial negative charge and the two hydrogen atoms acquire partial positive charge. The negatively charged oxygen forms two hydrogen bonds with two positively charged hydrogen atoms of two neighbouring molecules. Each oxygen atom is tetrahedrally surrounded by four hydrogen atoms as shown in visual. Hydrogen bonding in water results in a hydrogen bridge (HOH) network extending in three dimensions and the associated water molecule may be expressed as H Two O N. ii) Intramolecular hydrogen bonding. This type of bond is formed between hydrogen atom and Nitrogen, Oxygen or Flurine atom of the same molecule. This type of hydrogen bonding is commonly called chelation and is more frequently found in organic compounds. Intramolecular hydrogen bonding is possible when a six or five membered rings can be formed. Importance of H-bonding i) Life would have been impossible without liquid water which is the result of intermolecular H-bonding in it. ii) Hydrogen bonding increase the rigidity and strength of wood fibres and thus makes it an article of great utility to meet requirements of housing, furniture, etc. iii) The cotton, silk or synthetic fibres also own their rigidity and tensile strength to hydrogen bonding. iv) Most of our food materials such as carbohydrates and proteins also consist of hydrogen bonding. v) Hydrogen bonding also exists in various tissues, organs, skin, blood and bones.

This song explains the hydrogen bond attractive force and why water molecules have strong attractions despite their small relative size. Music and lyrics copyright 2007 by Mark Rosengarten. All rights reserved. Lyrics: Hydrogen bonds Bugs in a pond Walking across Some looking lost Why dont they fall in? Surface tension Hydrogen bonds Hydrogen bonds Small molecules They arent fools They can attract They wont attack H positive O negative Opposite ends They become friends H2O small Whys it liquid at all (CO2 gas Its got more mass) H2Os got Hydrogen bonds Bugs, they can cross Walking the pond Capillary Action, you see Cause it must be A high E.N.D. (ELECTRONEGATIVITY DIFFERENCE!!!) Got polar ends (The molecule bends) The O at the joint High boiling point Its not volatile (Just not its style) Hydrogen bonds Hydrogen bonds H on one side N, O or F on the other Its really polar And attracts like a mother! Dipole attraction from hell I love hydrogen bondssowell!!!!!

To see all my Chemistry videos, check out http://socratic.org/chemistry Hydrogen bonding can be so confusing, and in this video we talk about some common mistakes. Hydrogen bonds are intermolecular forces between molecules. They form because one atom has a high electronegativity, so it gets a partial negative charge, and the hydrogen gets a partial positive charge.
